ABSTRACT

A network fingerprint manager within an automatic content recognition (ACR) system may be operable to receive one or more versions of media content associated with a network. One or more proxy content may be generated by the network fingerprint manager for each version of the received media content. The network fingerprint manager may generate a set of fingerprints from a particular one of the generated one or more proxy content for each version of the received media content. The particular one being fingerprinted may comprise proxy content with highest quality among the generated proxy content. The set of fingerprints and corresponding content ID and media time for each version of the received media content may be stored. The network fingerprint manager may generate real-time fingerprints from content in a received network feed. The network fingerprint manager may compare the generated real-time fingerprints to the stored sets of fingerprints for matching.

DETAILED DESCRIPTION OF THE INVENTION

Certain embodiments of the invention can be found in a method and system for automatic content recognition network operations. In various embodiments of the invention, a network fingerprint manager, which is within an automatic content recognition (ACR) system, may be operable to receive one or more versions of media content associated with a network. One or more proxy content may be generated by the network fingerprint manager corresponding to each version of the received media content. The network fingerprint manager may be operable to generate a set of fingerprints from a particular one of the generated one or more proxy content for each version of the received media content. The particular one of the generated one or more proxy content may comprise proxy content with highest quality among the generated one or more proxy content. The network fingerprint manager may be operable to store the set of fingerprints and corresponding content ID and media time for each version of the received media content. In this regard, the received one or more versions of the media content may comprise a master version of the media content and/or one or more derivative versions that may be derived from the master version of the media content.

In an exemplary embodiment of the invention, the network fingerprint manager may be operable to compare each of the one or more derivative versions to the master version based on the stored set of fingerprints corresponding to each version of the received media content. A list of differences between each of the one or more derivative versions and the master version may be identified by the network fingerprint manager, based on the comparison and the associated media time. The network fingerprint manager may be operable to generate, for each version of the received media content, an interactive timeline that is linked to a media timeline corresponding to the fingerprinted proxy content. The interactive timeline may comprise event information associated with particular time(s) in the media timeline. The network fingerprint manager may be operable to store the generated interactive timeline for each version of the received media content. In such instances, the interactive timeline for each of the one or more derivative versions of the received media content may be generated utilizing the identified list of differences for each of the one or more derivative versions.

In an exemplary embodiment of the invention, the network fingerprint manager may be operable to receive a network feed associated with the network and generate real-time fingerprints from content in the received network feed. The generated real-time fingerprints may then be compared to the stored sets of fingerprints by the network fingerprint manager. In instances when a match occurs based on the comparison, the network fingerprint manager may be operable to determine, from among the stored content IDs and the stored media times, a particular content ID and a particular media time associated with a particular version of the received media content. The network fingerprint manager may then be operable to determine one or more particular event IDs from the stored interactive timeline, based on the determined particular content ID and the determined particular media time.

In an exemplary embodiment of the invention, the network fingerprint manager may be operable to generate, utilizing the determined one or more particular event IDs, an event timeline for identifying one or more events during presentation of the content of the network feed. In such instances, the generated event timeline may also comprise break structure information and/or break duration information, for example. In another exemplary embodiment of the invention, the network fingerprint manager may be operable to generate, utilizing the determined one or more particular event IDs, one or more event triggers for triggering one or more events in real-time during presentation of the content of the network feed.

FIG. 1A is a block diagram illustrating an exemplary communication system, in accordance with an embodiment of the invention. Referring to FIG. 1A, there is shown an ACR system 100, a network provider 102, a communication network 103, a service provider 104, a set-top box (STB) 105 and ACR-enabled devices 140. The ACR system 100 may comprise a network fingerprint manager 110. The ACR-enabled devices 140 may comprise an ACR-enabled connected TV device 141 and a paired device 143. The ACR-enabled connected TV device 141 may comprise an ACR module 142. The paired device 143 may comprise a companion application 144.

The ACR system 100 may comprise suitable logic, circuitry, interfaces and/or code that may be operable to support automatic content recognition operations in the ACR-enabled devices 140 such as the ACR-enabled connected TV device 141. The ACR system 100 may provide automatic content recognition applications and/or services to the ACR-enabled devices 140. The ACR system 100 may support a plurality of automatic content recognition technologies and may provide appropriate synchronization to the ACR-enabled connected TV device 141 and/or to the corresponding paired device 143. For example, the ACR system 100 may implement an abstraction layer to support a plurality of different fingerprinting technologies for the automatic content recognition. In this regard, the ACR system 100 may utilize fingerprints to identify content. The ACR system 100 may comprise the network fingerprint manager 110, for example. The network fingerprint manager 110 may comprise suitable logic, circuitry, interfaces and/or code that may be operable to manage or handle the offline fingerprinting portion of the operations performed by the ACR system 100. More details of the operation of the ACR system 100 are described below with respect to, for example, FIGS. 1B, 2A-2C and 3.

In an exemplary embodiment of the invention, the network fingerprint manager 110 in the ACR system 100 may be operable to generate fingerprints for one or more versions of media content received offline from the network provider 102. The network fingerprint manager 110 may store the fingerprints and maintain association of fingerprints with corresponding content IDs and media times. The network fingerprint manager 110 may then be operable to generate real-time fingerprints from content in a network feed received from the network provider 102. The generated real-time fingerprints may be compared to the stored fingerprints in the network fingerprint manager 110. In instances when the fingerprint comparison results in a match, the network fingerprint manager 110 may be operable to determine, from among the stored content IDs and the stored media times, a particular content ID and a particular media time associated with a particular version of the received media content. The network fingerprint manager 110 may then generate one or more event IDs based on the determined particular content ID and the determined particular media time. The generated one or more event IDs may then be utilized by the network fingerprint manager 110 to generate a real-time event timeline and/or one or more event triggers.

The network provider 102 may comprise suitable logic, circuitry, interfaces and/or code that may be operable to generate, capture and/or package content such as TV programming or multimedia content that may be distributed to display devices such as the ACR-enabled devices 140. For example, the content may be distributed to the ACR-enabled connected TV device 141 via the service provider 104 and the STB 105 or via the communication network 103. In an exemplary embodiment of the invention, the network provider 102 may provide content to the ACR system 100 for supporting the automatic content recognition operation.

The communication network 103 may comprise suitable logic, circuitry, interfaces and/or code that may be operable to provide communication among a plurality of entities via various wire-line and/or wireless technologies such as, for example, T1/E1, DSL, cable modem, FTTx, PLC and/or WiMAX. The communication network 103 may comprise, for example, Internet and/or another multimedia network. The communication network 103 may comprise one or more content delivery networks (CDNs) of the network provider 102, for example.

The service provider 104 may comprise suitable logic, circuitry, interfaces and/or code that may be operable to provide services using different access technologies to display devices such as the ACR-enabled devices 140. For example, the service provider 104 may provide connections to the ACR-enabled connected TV device 141 via the STB 105. Such connections may be utilized by the ACR-enabled connected TV device 141 to access content provided by the network provider 102.

The STB 105 may comprise suitable logic, circuitry, interfaces and/or code that may be operable to connect a display device such as the ACR-enabled connected TV device 141 to an external source of signals, such as the service provider 104, and to convert those signals into content that may be displayed on the screen of the ACR-enabled connected TV device 141. The STB 105 may be operable to provide processing associated with managing, delivering, and/or storing video content that may be displayed on the ACR-enabled connected TV device 141.

The ACR-enabled connected TV device 141 may comprise suitable logic, circuitry, interfaces and/or code that may be operable to receive content for presenting to a viewer such as the viewer 106. The content may comprise interactive content for the viewer 106 to interact. In addition to receiving content via the service provider 104 and the STB 105, the ACR-enabled connected TV device 141 may receive content from Internet via the communication network 103. In an exemplary embodiment of the invention, the ACR-enabled connected TV device 141 may comprise an ACR module 142. The ACR module 142 may comprise suitable logic, circuitry, interfaces and/or code that may be operable to provide automatic content recognition functions for the ACR-enabled connected TV device 141. The ACR module 142 may communicate with the ACR system 100, via the communication network 103, to support the automatic content recognition operations of the ACR-enabled connected TV device 141. For example, the ACR module 142 may support the automatic content recognition operations on video content provided by the network provider 102 via the service provider 104, or on video content being played back from a digital video recorder (DVR) or similar device.

The ACR module 142 may, for example, provide fingerprints to the ACR system 100 for matching. The ACR module 142 may receive ACR related information or content from the ACR system 100, for example. The ACR module 142 may be operable to run or execute a synchronous event manager to monitor events that occur internally to the ACR-enabled connected TV device 141 and/or events from sources external to the ACR-enabled connected TV device 141. The synchronous event manager may be run as a background process that may be transparent to the user. The synchronous event manager may be executed continuously during those periods where monitoring is to take place. An example of events from external sources may include, but need not be limited to, an overlay event corresponding to an automatic content recognition match. Examples of internal events may include, but need not be necessarily limited to, a process, an application, and/or a function corresponding to the automatic content recognition performed by the ACR-enabled connected TV device 141. In response to detected event triggers, the synchronous event manager may request and receive applications, such as user-interaction applications, which may be executed to produce interactive opportunities that may be presented to a viewer such as the viewer 106, for example. The synchronous event manager may be implemented, for example, in software, firmware and/or hardware.

The paired device 143 may comprise suitable logic, circuitry, interfaces and/or code that may be operable to pair with the ACR-enabled connected TV device 141 for automatic content recognition operations, including but not limited to second screen operations. Communication between the ACR-enabled connected TV device 141 and the paired device 143 may occur via a wireless communication protocol such as, for example, near field communication (NCF). The paired device 143 may pair with the ACR-enabled connected TV device 141 utilizing the companion application 144 downloaded in the paired device 143. For example, the companion application 144 may comprise a sync application downloaded in the paired device 143 from the ACR-enabled connected TV device 141. The paired device 143 may comprise, for example, a tablet, a laptop and/or a smartphone.

In operation, the network fingerprint manager 110 in the ACR system 100 may be operable to receive one or more versions of media content associated with a network. The network may be associated with a network provider such as the network provider 102. The media content may comprise, for example, programs, commercials, promotions and/or other pre-produced content. The one or more versions of the media content may be received offline from the network provider 102. The received one or more versions of the media content may comprise a master version of the media content and/or one or more derivative versions that may be derived from the master version of the media content. One or more proxy content may then be generated by the network fingerprint manager 110 corresponding to each of the received one or more versions of the media content. In such instances, the network fingerprint manager 110 may be operable to generate a set of fingerprints from a particular one of the generated one or more proxy content for each version of the received media content. In this regard, the fingerprinted particular one of the generated one or more proxy content may comprise proxy content with highest quality among the generated one or more proxy content, for example. The network fingerprint manager 110 may then store the set of fingerprints and corresponding content ID and media time for each version of the received media content.

In an exemplary embodiment of the invention, the network fingerprint manager 110 may be operable to compare each of the one or more derivative versions to the master version based on the stored set of fingerprints corresponding to each version of the received media content. A list of differences between each of the one or more derivative versions and the master version may be identified by the network fingerprint manager 110, based on the comparison and the associated media time. The network fingerprint manager 110 may be operable to generate, for each version of the received media content, an interactive timeline that is linked to a media timeline corresponding to the fingerprinted proxy content. In this regard, the interactive timeline may comprise event information associated with particular time(s) in the media timeline. The network fingerprint manager 110 may then store the generated interactive timeline for each version of the received media content. In such instances, the interactive timeline for each of the one or more derivative versions of the received media content may be generated utilizing the identified list of differences for each of the one or more derivative versions. In this regard, for example, the identified list of differences may be utilized to assist with automating the creation of a new interactive timeline for a unique edition of a program based on the network, the day and/or the time of day of which the program is to be presented.

In an exemplary embodiment of the invention, the network fingerprint manager 110 may be operable to receive a network feed associated with the network and generate real-time fingerprints from content in the received network feed. In this regard, the network feed may be received from the network provider 102 in real-time. The generated real-time fingerprints may then be compared to the stored sets of fingerprints by the network fingerprint manager 110. In instances when a match occurs based on the comparison, the network fingerprint manager 110 may be operable to determine, from among the stored content IDs and the stored media times, a particular content ID and a particular media time associated with a particular version of the received media content. The network fingerprint manager 110 may then be operable to determine one or more particular event IDs from the stored interactive timeline, based on the determined particular content ID and the determined particular media time.

In an exemplary embodiment of the invention, the network fingerprint manager 110 may be operable to generate, utilizing the determined one or more particular event IDs, an event timeline for identifying one or more events during presentation of the content of the network feed, for example, on the ACR-enabled connected TV device 141. In such instances, the generated event timeline may also comprise, for example, break structure information and/or break duration information. For example, the break structure information may comprise data, which indicate where each commercial break may begin or occur in the event timeline. The break duration information may comprise data which indicate the length of each commercial break. In this regard, for example, the ACR module 142 in the ACR-enabled connected TV device 141 may be operable to identify one or more events during the presentation of the content based on the one or more event IDs embedded in the event timeline.

In another exemplary embodiment of the invention, the network fingerprint manager 110 may be operable to generate, utilizing the determined one or more particular event IDs, one or more event triggers for triggering one or more events in real-time during presentation of the content of the network feed, for example, on the ACR-enabled connected TV device 141. In such instances, for example, the ACR module 142 in the ACR-enabled connected TV device 141 may be operable to fingerprint the presented content in real-time. The fingerprints of the presented content may be sent to the ACR system 100 for matching in real-time. The one or more event triggers may then be utilized to trigger one or more events in real-time based on the matching.

FIG. 1B is a high-level block diagram illustrating an exemplary automatic content recognition system with an abstraction layer, in accordance with an embodiment of the invention. Referring to FIG. 1B, there is shown an ACR system 100 that implements an abstraction layer to support fingerprinting technology from multiple vendors. The ACR system 100 is operable to support fingerprinting technology from multiple vendors and may be utilized to identify a network television station that provides content for display on a viewing screen based on the logo, symbol, sign, watermark, and/or text that are typically utilized to represent the network television station.

The ACR system 100 may comprise an offline fingerprint module 110, a monitor application module 115, a real-time event manager (RTEM) 120, a plurality of RTFSs 122, . . . , 124, fingerprint match systems 130, end-user devices 140, an applications and analytics module 150, and a timeline/event creation module 160. In some instances, at least some of the functions of the monitor application module 115 and of the RTEM 120 may be combined and may be provided by a common device or component of the ACR system 100.

The ACR system 100 may also comprise an NTP server 170 that is operable to provide synchronization to various parts of the ACR system 100 via a common reference clock. For example, the NTP server 170 may be operable to synchronize the operation of the RTEM 120 with the operation of the RTFSs 122, . . . , 124. The operations of the NTP server 170 may be based on, for example, the Internet Engineering Task Force (IETF) RFC 5905 “Network Time Protocol Version 4: Protocol and Algorithms Specification.”

The offline fingerprint module 110 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to handle the offline fingerprinting portion of the operations performed by the ACR system 100. The offline fingerprint module 100 may be operable to receive pre-recorded or offline content such as commercials, programs, and promotions, for example. In this regard, the offline fingerprint module 100 may be able to ingest and process content with defined interactivity. The monitor application module 115 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to process a network television feed and the content handled by the offline fingerprint module 110 to create a real-time timeline and/or real-time event triggers. During the process, the monitor application module 115, and/or the timeline/event creation module 160, may interact with backend analytics databases that comprise user-engagement data, for example. Some of the operations that may be performed by the offline fingerprint module 110 may comprise, for example, ingest operations, storage operations, monitoring operations, and/or content version comparison operations.

The RTEM 120 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to manage real-time events based on inputs provided by one or more sources. For example, the RTEM 120 may be operable to manage real-time events based on events stored in an interactive timeline archive, a network schedule, and/or those provided by an interactive director that may assign interactive event IDs to live programming as the network television feed is being fingerprinted in real time. Moreover, the RTEM 120 may be operable to trigger interactive events in legacy systems and/or in web-based systems. The RTEM 120 may be referred to as a real-time event trigger infrastructure, for example. The RTEM 120 may comprise a real-time event inserter (RTEI) (not shown), which is operable to insert the events into the RTFSs 122 . . . 124.

In accordance with an embodiment of the invention, the RTEM 120 may be operable to instruct the monitor application module 115, and/or the timeline/event creation module 160 to record the fingerprints associated with a live program as well as to store the corresponding set of events created during the live program in the interactive timelime archive. This enables playback of the program with interactivity even after expiration of the corresponding fingerprints in the vendor's third party database. This may occur in instances when there is a re-broadcast of the live event at a subsequent date. In the case of timeline based devices, the events may be stored and timeline retrieval may be enabled even during the active window of the corresponding fingerprints since there will be no available event-to-fingerprint association.

In accordance with an embodiment of the invention, the RTEM 120 may be operable to receive one or more inputs from a user (e.g., an interactive director), and to generate based on those inputs, interactive event identifiers that can be communicated to the fingerprint servers where they can be associated with or assigned to the video fingerprints generated by the fingerprint servers. The RTEM 120 may be operable to communicate the interactive event identifiers to a television system (e.g., legacy system) and/or to a web system. The interactive event identifiers may be utilized in the television system and/or in the web system to trigger interactive events. Moreover, the communication of the interactive event identifiers may be based on one or more of an EBIF, an HTTP live streaming (HLS), a satellite network protocol, or some other protocol.

In an embodiment of the invention, the Real-time event manager 120 may be operable to generate one or more signals that provide instructions to the RTFSs 122, . . . , 124 to enable the identification of a network television station based on the logo, symbol, sign, watermark, and/or text that are typically utilized to represent the network television station. The instructions may be related to information that is to be generated and/or provided to the end-user devices 140 for network television station identification. The instructions may indicate the type of information that is to be provided to the end-user devices 140 and/or when such information is to be provided. In some instances, a portion of the ACR system 100 other than the Real-time event manager 120, or in conjunction with the Real-time event manager 120, may generate the signals for providing instructions to the RTFSs 122, . . . , 124.

The RTFSs 122, . . . , 124 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to handle fingerprinting and fingerprint communications to the fingerprint match systems 130. Since each vendor or television manufacturer is likely to utilize its own fingerprint technology, each of the RTFSs 122, . . . , 124 may be a dedicated server for each of the fingerprint technologies supported by the ACR system 100. In some embodiments of the invention, a portion of the RTFSs 122, . . . , 124 may be operable to perform video fingerprinting while the remaining portion of the RTFSs 122, . . . , 124 may be operable to perform audio fingerprinting or some combination thereof. Fingerprint technologies from multiple vendors may utilize different computations to perform fingerprinting of video and/or audio frames. For example, each fingerprint technology may utilize a specific set of algorithms, parameters, operations, and/or data processing methods, for example.

In an embodiment of the invention, the RTFSs 122, . . . , 124 may be operable to receive one or more signals from the Real-time event manager 120 and/or from another portion of the ACR system 100 to enable the identification of a network television station based on the logo, symbol, sign, watermark, and/or text that are typically utilized to represent the network television station. The instructions may be utilized to determine and/or provide locations to the end-user devices 140 to take fingerprints of the video content being displayed on a viewing screen. In some instances, at least a portion of the fingerprinting locations may be provided by the Real-time event manager 120 and/or by another portion of the ACR system 100 through the instructions received by the RTFSs 122, . . . , 124. In other instances, the fingerprinting locations may be determined by the RTFSs 122, . . . , 124 based on locally and/or remotely stored information. Each fingerprinting location may comprise coordinates in a video frame (e.g., x coordinates, y coordinates) that indicate a particular region in the video frame to fingerprint.

The RTFSs 122, . . . , 124 may provide the fingerprinting locations for communication to the end-user devices 140, for example, in the form of fingerprint profiles. The fingerprint profiles may comprise fingerprinting locations and/or other information to be utilized by an end-user device for ACR fingerprinting. In some instances, the fingerprint profiles may be generated by the RTFSs 122, . . . , 124 in response to the instructions received. In other instances, the fingerprint profiles comprising the fingerprinting locations may be received by the RTFSs 122, . . . , 124 from the Real-time event manager 120 and/or from another portion of the ACR system 100. The fingerprint profile of a particular end-user device 140 may be updated based on an indication that additional and/or different locations may be needed during fingerprinting to identify the network television station logo or symbol being displayed on a viewing screen at the end-user device 140. The update may be generated by the corresponding RTFS and then communicated to the end-user device 140 or may be received by the corresponding RTFS from the Real-time event manager 120 and/or from another portion of the ACR system 100 and then communicated to the end-user device 140.

The indication that a fingerprint profile update may be needed may be the result of network operations that recognize that certain content is being broadcast by several network television stations concurrently (e.g., State of the Union address). In such instances, the fingerprinting locations being utilized may not analyze the region in a video frame where the logo of the network television station is displayed. Thus, providing additional fingerprinting locations in this region may enable detection and identification of the logo and, consequently, of the network television station.

The indication that a fingerprint profile update may be needed may also be the result of feedback provided by an end-user device 140. The feedback may indicate, for example, that the content being displayed has been identified but that the content may have originated in any one of several sources and the particular source of the content has not been identified. In such instances, the fingerprinting locations being utilized may not analyze the region in a video frame where the logo of the network television station is displayed. Thus, providing additional fingerprinting locations in this region may enable detection and identification of the logo and, consequently, of the source of the content.

In some instances, the fingerprint profile and/or the fingerprint profile update received by an end-user device may comprise information that indicates to the end-user device that any additional fingerprinting locations may be utilized automatically when the source (e.g., network television station) of a particular content is not initially identified.

In one or more embodiments of the invention, the RTFSs 122, . . . , 124 may be operable to communicate fingerprint profiles and/or fingerprint profile updates to the end-user devices 140 through the fingerprint match systems 130. Feedback and/or queries from the end-user devices 140 may be received by the RTFSs 122, . . . , 124 for processing. The RTFSs 122, . . . , 124 may in turn communicate information corresponding to the feedback and/or queries from the end-user devices 140 to the Real-time event manager 120 and/or to another portion of the ACR system 100 for further processing.

The fingerprint match systems 130 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to enable hosted services in the Internet for matching fingerprints produced by the RTFSs 122, . . . , 124 with fingerprints produced by the end-user devices 140. Each of the fingerprint match systems 130 corresponds to a particular ACR or fingerprint technology. In this regard, each of the fingerprint match systems 130 may be supported by a third party such as a TV manufacturer, for example.

The fingerprint match systems 130 may be operable to compare fingerprints produced by the end-user devices 140 with fingerprints provided by the RTFSs 122, . . . , 124. When matches occur, the fingerprint match systems 130 may indicate that interactive events are to take place in the end-user devices 140. These interactive events may allow a viewer to be presented with information on the screen or display of an ACR-based device and to interact with the device based on the information presented.

The end-user devices 140 may comprise a plurality of devices such as connected TVs, connected TV with paired devices (e.g., tablets), and second screen devices such as smartphones and tablets, for example. The ACR-based devices may be referred to as end-user devices, for example. Since each of the fingerprint match systems 130 supports a different ACR or fingerprint technology, those end-user devices 140 that support a particular fingerprint technology are operable to communicate with the corresponding fingerprint match systems 130 that support the same fingerprint technology. Moreover, when a secondary or paired device that supports a particular fingerprint technology is used, that device may also be able to communicate with the corresponding fingerprint match system 130 that supports the compatible fingerprint technology.

The end-user devices 140 may be operable to receive and utilize a fingerprint profile and/or a fingerprint profile update and to take fingerprints in a pre-determined number of locations in a video frame. Each fingerprinting location may be defined by a set of coordinates that describe a region in the video frame where a fingerprint of the video content is to be taken. The end-user devices 140 may be operable to receive a series of fingerprint profiles and/or fingerprint profile updates and may be operable to adjust ACR fingerprinting accordingly.

The applications and analytics module 150 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to provide data to the end-user devices 140, determine what platforms are to be served and when these platforms are to be served, handle communications with third-party partners and advertisers, handle communication with backend analytics databases, and determine unique responses for a given device request (e.g., fix targeting).

The timeline/event creation module 160 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to produce a timeline of the content in a program or show based on information provided by the monitor application module 115. The timeline/event creation module 160 may then provide the timeline created to the applications and analytics module 150 to have the timeline disseminated to the appropriate End-user devices 140 that may not support event-to-fingerprint association. Once the End-user devices 140 have the timeline for a particular program or show, they may monitor the program or show, relative to the timeline, and launch appropriate event requests when a specified point in the timeline indicates that a particular event is to take place.

Communication between the RTFSs 122, . . . , 124, and the fingerprint match systems 130 may occur through one or more wireless and/or wireline communication links. Similarly, communications between the fingerprint match systems 130 and the end-user devices 140 and/or the applications and analytics module 150 may occur through one or more wireless and/or wireline communication links. The communication links described above may support one or more communication protocols. For example, communication protocols based on Internet Protocol (IP) may be typically used. Accordingly, the RTFSs 122, . . . , 124, the fingerprint match systems 130, and the applications and analytics module 150 may comprise suitable logic, circuitry, code, and/or interfaces to enable the use of the communication protocols.

In operation, the monitor application module 115 and/or the RTEM 120 may generate and/or handle event identifiers or event triggers that correspond to specific times in a program. These event identifiers may be generated from live programming, from a network schedule, or from information provided by the offline fingerprint module 110. The event identifiers may be assigned to the appropriate fingerprints generated by the RTFSs 122, . . . , 124. Since each RTFS relies on a different fingerprint technology, system synchronization is needed to appropriately assign the event identifiers to the right spot on a video and/or audio sequence. Such synchronization may be achieved by the use of a common reference clock provided by the NTP server 170.

Each of the RTFSs 122, . . . , 124 may communicate the event identifiers and the fingerprints to its corresponding one of the fingerprint match systems 130. The fingerprint match systems 130 in turn receive fingerprints from their corresponding end-user devices 140 and try to match those fingerprints to the ones received from their corresponding RTFSs 122, . . . , 124. When a match occurs, the event identifier and/or other information may be passed to the appropriate ACR-based device. With this information, the ACR-based device may obtain, for example, interactive information (e.g., graphics) from the applications and analytics module 150. For example, a connected TV may receive code or data specific for that device from a content management system (CMS) via a cloud-based content delivery network (CDN). There may be other actions performed by the user in connection with the interactive event and/or other information presented or produced in connection with the interactive event.

In operation, the ACR system 100 may generate a fingerprint profile that may be communicated to one of the end-user devices 140. The fingerprint profile may be communicated through one or more of the Real-time event manager 120, one of the RTFSs 122, . . . , 124, and one of the fingerprint match systems 130. The fingerprint profile may comprise locations where the end-user device is to take fingerprints of the video content being reproduced by the device. Once the content is identified based on the fingerprints taken and subsequently matched in the corresponding fingerprint match system 130, it may be determined that the source of the content is not known. Knowing the source of the content may be needed in some instances to enable interactive events associated with that source on the end-user device. Otherwise, an interactive event from, for example, one network television station may occur when a viewer is watching programming provided by a different network television station.

When the source of the content is not known, the end-user device may automatically utilize additional locations provided in the fingerprint profile or in a fingerprint profile update. These locations may correspond to the region in the video frame where the network television station logo or symbol is typically placed. Once these fingerprints are taken, they may be compared to fingerprints of the network television station logo or symbol at the corresponding fingerprint match systems 130. When a match occurs and the logo is identified, the end-user device may be able to receive interactive event identifiers from the corresponding RTFS. Once these interactive event identifiers are received, the end-user device may communicate with the applications and analytics module 150 to enable the interactive events to occur.

FIGS. 2A-2C are each a block diagram that illustrate details of the exemplary automatic content recognition system with abstraction layer shown in FIG. 1 B, in accordance with embodiments of the invention. Referring to FIG. 2A, there is shown a portion 100 a of the ACR system 100 that may substantially correspond to at least portions of the offline fingerprint module 110, the monitor application 115, and the timeline/event creation module 160 described above with respect to FIG. 1. The portion 100 a may comprise a content ingest module 212, an offline fingerprint ingest server 214, a content version comparison module 216, and a fingerprint database 220. The portion 100 a may also comprise an interactive timeline creation module 218, an interactive timeline archive 222, the monitor application module 115, and the timeline/event creation module 160. Also shown are backend databases (DB) 200 a and 200 b connected to the timeline/event creation module 160 and a playout server 274 connected to the monitor application module 115.

The content ingest module 212 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to receive a media master 210, also referred to as an air master, which may comprise one or more programs, commercials, and/or promotions, for example. The content ingest module 212 may be operable to generate or create a set of proxy videos by encoding the media master 210 utilizing different resolutions. The highest quality proxy video may be provided as an input to the offline fingerprint ingest server 214 while the lowest quality proxy video may be provide to the interactive timeline creation module 218. The content ingest module 212 may also provide a content ID (CID) and other associated metadata (e.g., program data, frame number) that corresponds to the content in the media master 210.

The offline fingerprint ingest server 214 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to use a fingerprint computation or algorithm to fingerprint content and subsequently push the fingerprints for archival in the fingerprint database 220. In the offline fingerprint ingest server 214, the highest quality proxy video created by the content ingest module 212 may be fingerprinted and may be associated with the content ID and corresponding related metadata. In this regard, the offline fingerprint ingest server 214 may utilize an API to automatically ingest the media files and associated metadata from the content ingest module 212. A graphical user interface (GUI) may also be supported to manually ingest media files and to enter associated metadata.

The offline fingerprint ingest server 214 may be operable to provide a management interface for the fingerprint database 220 and/or the content version comparison module 216. For example, an API may be utilized to remove content from the fingerprint database 220. A GUI may also be supported to manually remove content from the fingerprint database 220. The offline fingerprint ingest server 214 may be operable to set priorities regarding the content to be ingested and processed. Moreover, the offline fingerprint ingest server 214 may be operable to support, among other features, the use of administration tools and the creation of reports, the ability to generate progress reports on processing content and errors, and/or recoverability after a shut down or crash.

The offline fingerprint ingest server 214 may be implemented utilizing multiple modules (not shown). These modules may be operable to perform one or more functions. Examples of those functions may comprise, without limitation, receiving the content to be fingerprinted in an input or watch folder, receiving and assigning CIDs and processing priority utilizing content ingest management tools, supporting an ACR process for writing fingerprints to the fingerprint database 220, and supporting administration tools utilized for monitoring and reporting.

The fingerprint database 220, which may also be referred to as a central fingerprint database, for example, may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to store fingerprints captured by the offline fingerprint ingest server 214 and maintain the association between the captured fingerprints and a particular CID and media time.

In an embodiment of the invention, the fingerprint database 220 may support queries from multiple monitor applications 224. For example and without limitation, as many as 50 monitor applications 224 may query the fingerprint database 220. In response to a query, the fingerprint database 220 may return a CID and a media time associated with the fingerprint in a very short period of time, typically in less than one second. For example and without limitation, the return time by the fingerprint database 220 may be less than 10 milliseconds.

The fingerprint database 220 may also be operable to respond to requests from the content version comparison module 216 to identify differences between the master versions in the fingerprint database 220 and derivative works also ingested into the fingerprint database 220. For example, a movie may have different cuts or versions depending on the time of day and/or the network in which it is to be shown. The corresponding master and the derivative works may be ingested, fingerprinted, and stored in the fingerprint database 220. The interactive timeline creation module 218 may have access to the various versions of a certain work but it can identify the master version from any of the other cuts or versions. Typically, a request is initiated by the content version comparison module 216 to identify the differences (e.g., deltas) between the master and selected derivative works. A “delta” file is returned to the interactive timeline creation module 218, which incorporates the changes from the master source and automatically generates a derivative event timeline. Multiple derivative works may be compared to the master in the content version comparison module 216 to reduce the processing necessary to handle the other versions.

The fingerprint database 220 may be implemented as a distributed, fault-tolerant database that is operable to support persistent storage of fingerprints. The fingerprint database 220 may be operable to store large amounts of content fingerprints. For example and without limitation, the fingerprint database 220 may store up to 25,000 hours of content fingerprints. The number of hours of content fingerprints that can be stored may vary based on the availability of storage capacity in the fingerprint database 220.

The fingerprint database 220 may also be operable to concurrently support the reception of content from multiple offline fingerprint ingest servers 214, respond to queries from multiple monitor applications 224, and/or respond to queries from multiple content version comparison modules 216. For example and without limitation, the fingerprint database 220 may receive content from up to 10 offline fingerprint ingest servers 214. In another example and without limitation, the fingerprint database 220 may respond to queries from up to 50 monitor applications 224. In yet another example and without limitation, the fingerprint database 220 may respond to queries from up to five content version comparison modules 216. The number of requests and/or of content version comparison modules 216 that can be supported by the fingerprint database 220 may vary based on the capacity of the fingerprint database 220.

The fingerprint database 220 may be operable to support, among other features, administrative tools and report generation, management tools to report errors, and/or recoverability after a shut down or crash.

The fingerprint database 220 may be implemented utilizing multiple modules (not shown). These modules may comprise a fingerprint storage module as well as other modules that are operable to support the process of ingesting content from the offline fingerprint ingest server 214, the process of responding with a CID and media time to the monitor application module 115, and/or the process of responding to the content version comparison module 216. One or more modules may also be implemented to support administrative tools, monitoring, and/or reporting, for example.

The content version comparison module 216 may comprise suitable logic, circuitry, code, and/or interface that may be operable as a tool that enables comparison of a master version of some content to a derivative version of that same content based on fingerprints stored in the fingerprint database 220. A derivative work or piece may refer to a version of a program, promotion, or commercial, for example, that is different from a master version of that same program, promotion, or commercial. The content version comparison module 216 may return a file listing the differences between the master version and the derivative work based on a time code. The file may be provided to the interactive timeline creation module 218, for example.

The content version comparison module 216 may be operable to identify sequences that have been edited to shorten the time of handling the derivative work, the insertion of new advertisement break locations, and/or the insertion of new content. An example of the insertion of new advertisement break locations may comprise the addition of black frames of between 5 and 15 seconds. An example of the insertion of new content may occur in instances when the derivative work is the director's cut rather than the original theatrical master. The content version comparison module 216 may pass or communicate a difference file to the interactive timeline creation module 218 to be utilized for automating the creation of a new interactive timeline for a unique edit of a program based on the network, the day, and/or the time of day on which the program is to be shown.

The content version comparison module 216 may also be operable to query the fingerprint database 220 for information (e.g., fingerprints) to perform version comparison, to identify advertisement break locations based on black frames of between 5 and 15 seconds, and/or to generate an extensible markup language (XML) or similar output file that indicates the differences between a derivative piece and a master version. Moreover, the content version comparison module 216 may support, among other features, the use of administration tools and the creation of reports, the ability to generate progress reports on processing content and errors, and/or recoverability after a shut down or crash.

The content version comparison module 216 may be implemented utilizing multiple modules (not shown). These modules may be operable to perform one or more functions such as, for example, querying the fingerprint database 220 and performing file comparison. One or more modules may also be implemented to support administrative tools, for monitoring, and/or reporting, for example. The monitor application module 115 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to ingest a live broadcast television linear video feed and fingerprint the content in the feed in real time. The live broadcast television linear video feed may also be referred to as a network television feed, for example. The live broadcast television linear video feed can be based on a Serial Digital Interface (SDI) video interface and/or on a High-Definition SDI (HD-SDI) video interface. These fingerprints may be compared by the monitor application module 115 against fingerprints stored in the fingerprint database 220. When the comparison results in a fingerprint match, the fingerprint database 220 may return to the monitor application module 115 the CID and the media time of that match. The CID and the media time may then be provided to the timeline/event creation module 226. An API may be utilized to handle the communication between the monitor application module 115 and the timeline/event creation module 226.

As noted above, the monitor application module 115 may be operable to support, for example, a SDI and/or a HD-SDI for input that are provided from the broadcast chain prior to encoding and uplink. In this regard, the broadcast chain may provide the network television feed to the monitor application module 115. Other interfaces and/or formats may also be supported.

The monitor application module 115 may function so that it operates ahead of any ACR-based device or viewer device that is in the field, such as in a user's home, for example. Although the amount of time that the monitor application module 115 may be ahead from ACR-based devices in the field may vary, in a typical case the monitor application module 115 may be approximately at least 3 seconds ahead, for example.

The monitor application module 115 may be operable to query the fingerprint database 220 to determine the CID and the media time or media timeline. The monitor application module 115 may be operable to support an API that enables the monitor application module 115 to report the CID and the media time to a real-time event trigger infrastructure that is represented by the label “A” in FIG. 2A. Moreover, the monitor application module 115 may support, among other features, the use of administration tools and the creation of reports, the use of management tools for reporting errors, and/or the handling of failover/recovery operations.

The monitor application module 115 may be implemented utilizing multiple modules (not shown). These modules may comprise a module for video capture from an SDI/HD-SDI capture card, a module that provides real-time fingerprinting and querying of the fingerprint database 220, and a module that supports an API to communicate the CID, media time, and other data (e.g., duplicate CIDs, mediatime, confidence, number of seconds). One or more modules may also be implemented to support administrative tools, monitoring, and/or reporting, for example.

The timeline/event creation module 226, which may be implemented as part of the monitor application 226, may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to query the interactive timeline archive 222 for events associated with the CID. The timeline/event creation module 226 may be operable to utilize the CID and the media time received by the monitor application module 115 from the fingerprint database 220 to look up event IDs in the interactive timeline archive 222. The event IDs are used to create a real-time timeline (i.e., schedule) in XML or other standard data format and real-time event triggers.

The interactive timeline creation module 218 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to utilize the proxy video generated by the content ingest module 212 and link an interactive timeline against the fingerprinted media. The interactive timeline may comprise one or more event IDs associated with a particular time in a program, commercial, or promotion. The interactive event IDs may be referred to as interactive event IDs, for example. The interactive timeline archive 222 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to store multiple interactive timelines.

In operation, the air master 210 is received and ingested by the content ingest module 212 and a proxy video is created. The highest quality proxy video generated by the content ingest module 212 may be provided to the offline fingerprint ingest server 214 while a lower quality proxy video generated by the content ingest module 212 may be provided to the interactive timeline creation module 218. The offline fingerprint ingest server 214 may fingerprint the high quality proxy video and may send the fingerprints to the fingerprint database 220 for archiving. In addition to the fingerprints, CIDs and media times may be stored in the fingerprint database 220.

The interactive timeline creation module 218 may receive the proxy video and may link event IDs that represent certain desired interactive events with the program's timeline to generate an interactive timeline. The interactive timeline may be stored in the interactive timeline archive 222.

When a derivative piece or different version from a master version is ingested, the content version comparison module 216 may compare fingerprints of the master version with fingerprints from the derivative piece to generate a difference file that is provided to the interactive timeline creation module 218. The interactive timeline creation module 218 may utilize the difference file to create an interactive timeline for the derivative piece from an interactive timeline previously generated for the master version.

The monitor application module 115 receives a network television feed and fingerprints the video content in the feed. The fingerprints generated are compared to those stored in the fingerprint database 220 to obtain CIDs media times, and potentially to act when a match is detected. The interactive timeline archive 222 may be queried to obtain event IDs associated with the CIDs. When event IDs are obtained, the timeline/event creation module 226 may generate a real-time timeline XML (or similar data format) feeds and may also generate real-time event triggers that may be communicated to a real-time event trigger infrastructure.

Referring to FIG. 2B, there is shown a portion 100 b of the ACR system 100 that may comprise the RTEM 120, video RTFSs 240, 242, and 244, an audio RTFS 246, video fingerprint vendors 250, 252, and 254, and an audio fingerprint vendor 256. The number of video RTFSs and corresponding video fingerprint vendors as well as the number of audio RTFSs and corresponding audio fingerprint vendors shown in FIG. 2B are provided by way of illustration and not of limitation. More or fewer video RTFSs and corresponding video fingerprint vendors may be utilized in the ACR system 100. Similarly, the ACR system 100 may utilize more or fewer audio RTFSs and corresponding audio fingerprint vendors than those shown in FIG. 2B. The NTP server 170 of FIG. 1 is shown providing reference timing to the RTEM 120 and the RTFSs 240, 242, 244, and 246.

Also shown in FIG. 2B are various viewer devices such as connected TVs with paired devices 260 and 262, connected TVs without paired devices 264, and mobile devices 266, such as smartphones (e.g., iPhone, Android, etc.) and tablets (e.g., iPad, Samsung Galaxy, etc.). A paired device associated with the connected TVs may be a tablet, smartphone, or other like devices, for example.

The viewer devices 260 may be operable to utilize the same video fingerprinting technology (e.g., video ACR) utilized by the video RTFS 240 and supported by the video fingerprint vendor 250. The video fingerprint vendor 250 may be a vendor, manufacturer, or other third-party service provider that may comprise suitable logic, circuitry, code, and/or interfaces operable to provide hosted services over the Internet (e.g., cloud computing, etc.) for the viewer devices 260. These services may comprise video fingerprint matching as well as the delivery of any interactive event IDs associated with a match. In addition, the video fingerprint vendor 250 may provide a network television station identifier and/or network timing information (e.g., heartbeat message or NTP-based network timestamp) that may be utilized by the viewer devices 260 for ACR-related applications and/or to maintain synchronization with the network television feed. The viewer devices 260 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to take and send video fingerprints to the video fingerprint vendor 250 for matching.

The viewer devices 262 may be operable to utilize the same video fingerprinting technology utilized by the video RTFS 242 and supported by the video fingerprint vendor 252. The video fingerprinting technology utilized by the viewer devices 262 may be different from that utilized by the viewer devices 260. The video fingerprint vendor 252 may be a vendor, manufacturer, or other third-party service provider that may comprise suitable logic, circuitry, code, and/or interfaces operable to provide hosted services over the internet for the viewer devices 262. These services may comprise video fingerprint matching as well as the delivery of any interactive event IDs associated with a match. In addition, the video fingerprint vendor 252 may provide a network television station identifier and/or network timing information that may be utilized by the viewer devices 262 for ACR-related applications and/or to maintain synchronization with the network television feed. The viewer devices 262 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to take and send video fingerprints to the video fingerprint vendor 252 for matching.

The viewer devices 260 and 262 may be operable with a second device (e.g., smartphones, tablets) that may be paired to the parent device. In this regard, the second device may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to take and send video and/or audio fingerprints to a corresponding video fingerprint vendor for matching or enable suitable pairing with the parent device to provide analogous functionality.

The viewer devices 264 may utilize the same video fingerprinting technology utilized by the video RTFS 244 and supported by the video fingerprint vendor 254. The video fingerprint vendor 254 may be a vendor, manufacturer, or other third-party service provider that may comprise suitable logic, circuitry, code, and/or interfaces operable to provide hosted services over the Internet for the viewer devices 264. These services may comprise video fingerprint matching as well as the delivery of any interactive event IDs associated with a match. In addition, the video fingerprint vendor 254 may provide a network television station identifier and/or network timing information that may be utilized by the viewer devices 264 for ACR-related applications and/or to maintain synchronization with the network television feed. The viewer devices 264 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to take and send video fingerprints to the video fingerprint vendor 254 for matching.

The viewer devices 266 may utilize the same audio fingerprinting technology (e.g., audio ACR) utilized by the audio RTFS 246 and supported by the audio fingerprint vendor 256. The viewer devices 266 may be referred to as second-screen devices, for example. The audio fingerprint vendor 256 may be a vendor, manufacturer, or other third-party service provider that may comprise suitable logic, circuitry, code, and/or interfaces operable to provide hosted services over the Internet for the viewer devices 266. These services may comprise audio fingerprint matching as well as the delivery of any interactive event IDs associated with a match. In addition, the audio fingerprint vendor 256 may provide a network television station identifier and/or network timing information that may be utilized by the viewer devices 260 for ACR-related applications and/or to maintain synchronization with the network television feed. The viewer devices 266 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to take and send audio fingerprints to the audio fingerprint vendor 256 for matching.

The RTFSs 240, . . . , 246 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to perform fingerprinting of content received from the network television feeds. Each video RTFS may utilize a different video fingerprinting technology or computation from that utilized by the other video RTFSs. Similarly, when more than one audio RTFS is utilized, its audio fingerprint technology or computation may be different from that utilized by the other audio RTFSs. That is, since each vendor supports a different technology for handling fingerprinting, dedicated RTFSs may be needed for each vendor and for that vendor's corresponding viewer devices. The RTFSs 240, . . . , 246 may be operable to send fingerprints, interactive event IDs, television network station identifiers, and/or network timing information to their corresponding fingerprint vendors through one or more networks (e.g., wireline networks, wireless networks) and/or by utilizing one or more communication protocols.

The RTEM 120 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to perform real-time event triggering. In this regard, the RTEM 120 may be operable to manage real-time events based on inputs from different sources. For example, the RTEM 120 may comprise a pre-recorded event trigger module 232 to provide real-time triggering from the monitor application module 115, a time-scheduled event trigger module 234 to schedule the occurrence of a trigger based on a broadcast schedule, and a live event trigger module 236, each of which is operable to handle a different type of input.

The pre-recorded event trigger module 232 may be operable to receive real-time event triggers from the timeline/event creation module 226 described above with respect to FIG. 2A. These interactive event IDs may be stored in the interactive timeline archive 222 and may be utilized by the pre-recorded event trigger module 232 to assign interactive events via defined APIs to fingerprints generated as the network television feeds are fingerprinted by the RTFSs 240, . . . , 246.

The time-scheduled event trigger module 234 may be operable to receive a network or broadcast schedule and to assign, based on the network schedule, interactive events to fingerprints generated as the network television feed is fingerprinted by the RTFSs 240, . . . , 246. The network or broadcast schedule can be in XML format or in some other structured data format, for example.

The live event trigger module 236 may be operable to received interactive event IDs assigned by an interactive director to live programming. The interactive director may be an operator that is responsible for inserting events into the live broadcast. For pre-produced content, for example, the interactive director may watch an episode and may determine when an interactive element is to take place, when to push a trivia question, when to push a fun fact, when to drive social engagement, and/or when to share a clip or post a comment. For live content, for example, the interactive director may determine when to trigger a poll question and may manage the prompting of interactive games and determine when to trigger particular questions to engage viewers in a friendly competition. For advertisement, for example, the interactive director may determine when to bring up an offer, when to prompt to prepare for interaction or interaction event, and/or determine how long to leave interactive content on screen based on frequency rules and/or time of day. When advertisement is pre-fingerprinted, for example, interactive advertisement activities may occur automatically.

The RTEM 120 may also be operable to trigger interactive events in legacy television systems and/or in web-based systems. The infrastructure provided by the RTEM 120 may support the triggering of interactive events against applications and set-top boxes (STBs) via enhanced television binary interchange format (EBIF), hypertext transfer protocol (HTTP) live streaming (HLS) via ID3 tags, and satellite delivery systems (e.g., DISH, DirectTV) via the appropriate mechanism on the corresponding STB software platform. For HLS an ID3 tag may be utilized for sending interactive event IDs, for example.

The RTEM 120 may be operable to assign interactive event IDs to particular fingerprints in a sequence of audio or video fingerprints generated by the RTFSs 240, . . . , 246. The RTEM 120 may also be operable to provide television network station identifiers and/or network timing information associated with any sequence of fingerprints.

In the example shown in FIG. 2B, the RTFSs 240, . . . , 246 may correspond to the RTFSs 122, . . . ,124, the fingerprint vendors 250, . . . , 256 may correspond to the fingerprint match systems 130, and the viewer devices 260, . . . , 266 may correspond to the ACR-based devices 140, which are illustrated in FIG. 1.

In operation, the RTEM 120 may generate and/or handle one or more interactive event IDs that correspond to a particular set of fingerprints generated by the RTFSs 240, . . . , 246. The RTEM 120 may have determined the interactive event IDs based on live event inputs, time-scheduled event inputs, and/or pre-recorded event inputs. The RTEM 120 may assign or associate the interactive event IDs to their appropriate fingerprints based on the synchronization of its operation to the operation of the RTFSs 240, . . . , 246 via broadcast NTP. The RTEM 120 may also provide television network station identifiers and/or network timing information to the RTFSs 240, . . . , 246. The RTFSs 240, . . . , 246 may communicate the fingerprints, interactive event IDs, the television network station identifiers, and/or the network timing information to their corresponding fingerprint vendors.

The client or viewer devices may take and send fingerprints to their corresponding fingerprint vendors, which in turn determine whether there is a match with the fingerprints received from the RTFSs. Upon detection or determination of a match, the fingerprint vendors may return to the viewer device various pieces of information, including but not limited to network timing information and any interactive event ID that is triggered as a result of the match.

The portion 100 b in FIG. 2B may illustrate the implementation of an abstraction layer that enables the ACR system 100 to assign the same interactive event identifiers to different sets of video and/or audio fingerprints that are generated from different fingerprint technologies. That is, by appropriately timing the assignment of interactive event identifiers to multiple sequences of fingerprints that are generated from the same video content but with different fingerprinting technologies, the ACR system 100 may be able to support fingerprinting technologies from multiple vendors. Such implementation may provide flexibility by enabling a vendor to update its fingerprinting technology without affecting other fingerprinting technologies. Moreover, the architecture of the ACR system 100 may provide scalability by enabling new or additional fingerprint technologies from other vendors or from the same vendors to be added and supported.

Referring to FIG. 2C, there is shown a portion 100 c of the ACR system 100 that may comprise the viewer devices 260, . . . , 266 and the fingerprint vendors 250, . . . , 256 shown in FIG. 2B. Also shown are application data servers 270, an analytics module 272, a rules engine 274, a cloud-based content delivery network (CDN) 275, and a content management system (CMS) 276. In addition, FIG. 2C shows a user response module 280 and third-party partners/advertisers 282.

The application data servers 270 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to receive from a viewer device information related to an interactive event ID, a network television station, fingerprinted broadcast time, CID and additional data, and/or a device type. The information may be provided by the viewer device in response to a match between a fingerprint taken by the device and a fingerprint taken by the corresponding RTFS. Once a match occurs and the viewer device obtains the appropriate information from its corresponding fingerprint vendor, the viewer device may communicate the information to the application data servers 270, which in turn returns the appropriate content that corresponds to the interactive event ID and related data in a callback. Content may be pushed to a second screen or device paired with a connected TV that is logged in to an appropriate application or Web page.

The application data servers 270 may be operable to send information to the analytics module 272 as to what kind of interactions (e.g., clicks, selections, options, viewing behavior on a given broadcaster's network) are taking place in a viewer device. The application data servers 270 may be operable to handle the flow of user response data with third-party partners and/or advertisers 282. The user response data may comprise, but need not be limited to, TV IDs, coupon IDs, and event IDs, for example. Communication of the user response data between the application data servers 270 and the third-party partners/advertisers 282 may be handled by the user response module 280, for example. The application data servers 270 may be operable to call the CMS 276 for text, banners, graphics, overlays, and/or video, for example.

The application data servers 270 may also be operable to deliver event schedules to viewer devices, to deliver correct content uniform resource locator (URL) based on the type of viewer device, to integrate with a variety of back-end systems, to integrate with polling servers (not shown), to integrate with gaming services such as leader boards, and/or to integrate with customer databases such as those used in connection with store user preferences and social circle members, for example. With respect to integrating with back-end systems, the application data servers 270 may, for example, integrate with social networks for storage of tweets for later playback and/or to filter comments and push back to applications.

The rules engine 274 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to determine which platforms (e.g., viewer devices) are to be served and when are those platforms to be served by the application data servers 270. The rules engine may be preconfigured and/or dynamically configured.

The CMS 276 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to store the content that is delivered to the viewer devices. For example, content that may be delivered may comprise text, banners, graphics, overlays, and video. Other examples of content may comprise polls and fun facts, clips to share, games and trivia, and advertising content. These examples are provided by way of illustration and not of limitation. Accordingly, other examples of contents that may be utilized for user interactive events with the viewer devices may also be stored in the CMS 276.

The CMS 276 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to enable communication between the application data servers 270 and the CDN 275. The CMS 276 is operable to post assets to the CDN 275. ACR-based devices are operable to download the assets (graphics, banners, overlays, video, etc) from the CDN 275.

The analytics module 272 may comprise suitable logic, circuitry, code, and/or interfaces that may be operable to receive user interaction information from the application data servers 270 or directly from the viewing devices. The analytics module 272 may comprise one or more back-end databases to store, mange, and/or process user information.

In operation, content may be provided by the application data servers 270 to one of the viewer devices 260, . . . , 266 in response to receiving an interactive event ID, a network television station, device type, and other data from that viewer device. Rules regarding which viewer device is to be served, and when the device may be served, may be determined by the rules engine 274. The content to be served by the application data servers 270 to the viewer device may be stored in the CMS 276.

The analytics module 272 may determine which viewers are interacting with content and what those viewers are watching based on information received from the application data servers 270 or directly from the viewing devices. Viewer responses that result from interactive events may be handled by the user response module 280, which in turn communicates with third-party partners/advertisers 282.

The third-party partners/advertisers 282 may comprise and/or be connected to advertisement servers and/or one or more fulfillment systems. The advertisement servers may be utilized to deliver advertisement overlays to ACR-based applications running on viewer devices. The advertisement servers may also be operable to support the tracking of user impressions and click-throughs and/or to perform other advertising-related functions.

The fulfillment systems may utilize one or more technologies to fulfill viewer requests that occur in connection with ACR-based applications and user interaction. Examples of such technologies may comprise, but need not be limited to, coupon delivery technologies, technologies for movie ticket purchases and delivery, and/or short message service/multimedia messaging service (SMS/MMS) gateways.

FIG. 3 is a high-level functional diagram of an exemplary work flow for an automatic content recognition with an abstraction layer, in accordance with an embodiment of the invention. Referring to FIG. 3, there is shown a work flow 300 that illustrates the high-level functions of the ACR system 100 described above with respect to FIGS. 1A-2C. In the work flow 300, at step 310, television network operations may generate or produce air masters 210 or other similar reference content for various programs, promotions, and/or commercials. At step 320, the content may be ingested by a content acquisition operation, which may be performed by, for example, the content ingest module 212. At step 330, the content, which may be processed into proxy content such as proxy videos at step 320, may be fingerprinted and archived. The fingerprinting may be performed by, for example, the offline fingerprint ingest server 214, and the archiving may be performed by, for example, the fingerprint database 220.

At step 332, the proxy content may be utilized by a series of interactive event content timeline association tools to produce and archive interactive timelines. The tools may be, for example, the interactive timeline creation module 218 and/or the content version comparison module 216. The archiving may be performed by, for example, the interactive timeline archive 222.

At step 334, backend databases 229 may be utilized to perform the operations corresponding to steps 332 and 340. The backend databases 229 may be utilized to collect and provide user-engagement data. The backend databases 229 may be utilized to provide break structure information and/or break duration information.

At step 336, a broadcast feed may be generated, which may comprise at least some of the content ingested during the content acquisition operations in step 320. The broadcast feed may be a network feed or network television feed 228, for example. At step 340, the broadcast feed may be monitored by, for example, the monitor application 224. The output from the network monitoring may be provided to step 342, where real-time program event timeline creation (e.g., XML file creation) may be performed by, for example, the timeline/event creation module 226. The output from the network monitoring may also be provided to step 344, where event triggers may be generated by, for example, the timeline/event creation module 226.

At step 344, an event manager, such as the event manager 230, for example, may receive the event triggers and may assign interactive event IDs to fingerprints generated from network television feeds. The interactive event IDs and other information may be communicated by the fingerprint servers (e.g., RTFSs 240, . . . , 246) to corresponding fingerprint match systems such as the fingerprint vendors 250, . . . , 256, for example.

At step 350, social and other like networks may be integrated with application data services such as those provided by the application data servers 270. At step 352, the television network media operations may provide push events, which in turn may be provided to or integrated with the application data servers 270 at step 354. Moreover, at step 356, rules from, for example, the rules engine 274 may be provided to the application data servers 270.

At step 360, the real-time program event timeline from step 342 as well as the real-time event triggers from step 344 may be received by the application data servers 270 to perform application services such as those described above with respect to FIG. 2C. The application services at step 360 may be integrated with response collection operations at step 370. At step 372, collected responses and end-user information may be analyzed by, for example, the analytics module 272. Moreover, the collected responses may be processed by third-parties such as the third-party partners/advertisers 282, for example. In this regard, the functions and/or services provided by the third-party partners/advertisers 282 may be integrated with the application services in step 374.

FIG. 4 is a flow chart illustrating exemplary steps for automatic content recognition network operations, in accordance with an embodiment of the invention. Referring to FIG. 4, the exemplary steps start at step 401. In step 402, the content ingest module 212 in the network fingerprint manager 110 that is within the ACR system 100 may be operable to receive one or more versions of media content from the media master 210 associated with a network. The network may be associated with the network provider 102, for example. The received one or more versions of the media content may comprise, for example, a master version and/or one or more derivative versions that may be derived from the master version. In step 403, the content ingest module 212 in the network fingerprint manager 110 may be operable to generate one or more proxy content corresponding to each version of the received media content. In step 404, the offline fingerprint ingest server 214 in the network fingerprint manager 110 may be operable to generate a set of fingerprints from a particular one of the generated one or more proxy content for each version of the received media content. In this regard, the fingerprinted particular one of the generated one or more proxy content may comprise proxy content with highest quality among the generated one or more proxy content. In step 405, the fingerprint database 220 in the network fingerprint manager 110 may be operable to store the set of fingerprints and corresponding content ID and media time for each version of the received media content.

In step 406, the interactive timeline creation module 218 in the network fingerprint manager 110 may be operable to generate, for each version of the received media content, an interactive timeline that is linked to a media timeline corresponding to the fingerprinted proxy content. In this regard, the interactive timeline may comprise event information associated with particular time(s) in the media timeline. The interactive timeline for each of the one or more derivative versions of the received media content may be generated utilizing an identified list of differences between the master version and each of the one or more derivative versions. In such instances, the identified list of differences may be identified by the content version comparison module 216 in the network fingerprint manager 110. In step 407, the generated interactive timeline for each version of the received media content may be stored in the interactive timeline archive 222 in the network fingerprint manager 110. The exemplary steps may proceed to the end step 408.

FIG. 5 is a flow chart illustrating exemplary steps for real-time network monitoring, in accordance with an embodiment of the invention. Referring to FIG. 5, the exemplary steps start at step 501. In step 502, the monitor application 224 in the network fingerprint manager 110 that is within the ACR system 100 may be operable to receive a network feed 228 associated with a network. The network may be associated with the network provider 102. In step 503, the monitor application 224 may be operable to generate real-time fingerprints from content in the received network feed 228. In step 504, the monitor application 224 may be operable to compare the generated real-time fingerprints to stored sets of fingerprints. In this regard, the stored sets of fingerprints may be stored offline in the fingerprint database 220 in the network fingerprint manager 110. In step 505, in instances when a match occurs based on the comparison, the monitor application 224 may be operable to determine, from among stored content IDs and stored media times, a particular content ID and a particular media time associated with a particular version of media content. In this regard, the stored content IDs and the stored media times may be stored offline in the fingerprint database 220 in the network fingerprint manager 110.

In step 506, the timeline/event creation module 226 in the network fingerprint manager 110 may be operable to determine one or more particular event IDs from a stored interactive timeline, based on the determined particular content ID and the determined particular media time. In this regard, the stored interactive timeline may be stored offline in the interactive timeline archive 222 in the network fingerprint manager 110. In step 507, the timeline/event creation module 226 may be operable to generate, utilizing the determined one or more particular event IDs, an event timeline and/or one or more event triggers. In this regard, the generated event timeline may also comprise break structure information and/or break duration information. The break structure information and the break duration information may be communicated from the backend databases 229. The exemplary steps may proceed to the end step 508.

In various embodiments of the invention, a content ingest module 212 in a network fingerprint manager 110, which is within an ACR system 100, may be operable to receive one or more versions of media content from a media master 210 associated with a network. The network may be associated with a network provider such as the network provider 102. The media content may comprise, for example, programs, commercials, promotions and/or other pre-produced content. The received one or more versions of the media content may comprise a master version of the media content and/or one or more derivative versions of the media content. The one or more derivative versions may be derived from the master version of the media content. One or more proxy content may then be generated by the content ingest module 212 in the network fingerprint manager 110 corresponding to each of the received one or more versions of the media content. In such instances, an offline fingerprint ingest server 214 in the network fingerprint manager 110 may be operable to generate a set of fingerprints from a particular one of the generated one or more proxy content for each of the received one or more versions of the media content. In this regard, the fingerprinted particular one of the generated one or more proxy content may comprise proxy content with highest quality among the generated one or more proxy content, for example. The set of fingerprints, and corresponding content ID and media time, for each of the received one or more versions of the media content may then be stored in a fingerprint database 220 in the network fingerprint manager 110.

In an exemplary embodiment of the invention, a content version comparison module 216 in the network fingerprint manager 110 may be operable to compare each of the one or more derivative versions to the master version based on the stored set of fingerprints corresponding to each version of the received media content. A list of differences between each of the one or more derivative versions and the master version may be identified by the content version comparison module 216 in the network fingerprint manager 110, based on the comparison and the associated media time. An interactive timeline creation module 218 in the network fingerprint manager 110 may be operable to generate, for each of the received one or more versions of the media content, an interactive timeline that is linked to a media timeline corresponding to the fingerprinted proxy content. In this regard, the interactive timeline may comprise event information associated with particular time(s) in the media timeline. The generated interactive timeline for each of the received one or more versions of the media content may then be stored in an interactive timeline archive 222 in the network fingerprint manager 110. In such instances, the interactive timeline for each of the one or more derivative versions of the received media content may be generated utilizing the identified list of differences for each of the one or more derivative versions. In this regard, for example, the identified list of differences may be utilized to assist with automating the creation of a new interactive timeline for a unique edition of a program based on the network, the day and/or the time of day of which the program is to be presented.

In an exemplary embodiment of the invention, a monitor application 224 in the network fingerprint manager 110 may be operable to receive a network feed 228 associated with the network and generate real-time fingerprints from content in the received network feed 228. In this regard, the network feed 228 may be received from the network provider 102 in real-time. The generated real-time fingerprints may then be compared, by the monitor application 224 in the network fingerprint manager 110, to the stored sets of fingerprints that are stored in the fingerprint database 220. In instances when the comparison results in a match, the monitor application 224 may be operable to determine, from among the stored content IDs and the stored media times, a particular content ID and a particular media time associated with a particular version of the received media content. A timeline/event creation module 226 in the network fingerprint manager 110 may then be operable to determine one or more particular event IDs from the stored interactive timeline that is stored in the interactive timeline archive 222, based on the determined particular content ID and the determined particular media time.

In an exemplary embodiment of the invention, the timeline/event creation module 226 in the network fingerprint manager 110 may be operable to generate, utilizing the determined one or more particular event IDs, an event timeline for identifying one or more events during presentation of the content of the network feed, for example, on the ACR-enabled connected TV device 141. In such instances, the generated event timeline may also comprise, for example, break structure information and/or break duration information. The break structure information and the break duration information may be communicated from the backend databases 229. The break structure information may comprise, for example, information indicating where each commercial break may begin or occur in the event timeline. The break duration information may comprise, for example, information indicating the length of each commercial break. In this regard, for example, an ACR module 142 in an ACR-enabled connected TV device 141 may be operable to identify one or more events during the presentation of the content based on the one or more event IDs embedded in the event timeline.

In another exemplary embodiment of the invention, the timeline/event creation module 226 in the network fingerprint manager 110 may be operable to generate, utilizing the determined one or more particular event IDs, one or more event triggers for triggering one or more events in real-time during presentation of the content of the network feed 228, for example, on an ACR-enabled connected TV device 141. In such instances, for example, an ACR module 142 in the ACR-enabled connected TV device 141 may be operable to fingerprint the presented content in real-time. The fingerprints of the presented content may be sent to fingerprint match systems 130 in the ACR system 100 for matching in real-time. The one or more event triggers may then be utilized to trigger one or more events in real-time based on the matching.
